EI LLSWORTH J. HANNA, OF EVANSTON, ILLINOIS AWNING MECHANISM OR THE LIKEApplication filed November 7, 1929.

The present invention relates to barrier or deflector mechanisms foropenings and more in particular to movable and adjustable awningmechanisms or the like.

Among the objects of the invention is to provide a novel barrier ordeflector mechanism for an opening and having a plurality of pivotallyconnected vanes or slats being supported and carried by substantiallyrigid VLU and extensible means.

Another object of the invention is to provide a novel means forsupporting the vanes of a barrier or deflector mechanism for openings,this novel means comprising a substan- 97-1 tially rigid and extensiblemeans for support of the ends of the slats or vanes, and being adaptedto be collapsible or contracted when not in use and to be extended intoany desired position for varying the angularity 2 of the vanes or slatssupported thereby.

The invention comprehends the idea of pivotally mounting the extensiblemeans adjacent the sides of the opening and providing suitable means forengagement with the extensible means for movement of the awning orbarrier mechanisms outwardly and away from the openingupon a lowering ofthe same.

Another novel feature of the invention is t the provision of crossmembers or rods secured to certain parts of the extensible means forpreventing lateral movement of these extensible means, these rodsadapted to have secured thereto asuitable covering to pro- 5 vide aplurality of vanes for'the barrier or deflecting mechanism.

The invention further comprehends the idea of providing novel pantographmechanisms for attachment to the sides of the opening, certain of thelinks of these mechanisms adapted to have attached or secured to theends thereof, cross members or rods, the adjacent rods or cross membersof the same links having a covering secured to the same for providing aplurality of vanes or slats for the barrier or deflector.

Another object ofthe invention is to provide novel means for reinforcingand maintaining the rodsor cross-members between 50 the pantographmechanisms in alignment,

such means comprising strips or the like connected or attached betweenthe adjacent rods of the same link and spaced therealong.

The invention further comprehends the idea of providing a plurality ofextensible means or pantograph mechanism secured to or pivotallyconnected adjacent each side of an opening and carrying therebetween aplurality of vanes or slats, means being provided for raising andlowering these mechanisms simultaneously.

A further object of the invention is to provide a novel arrangement ofmeans for raising and lowering a plurality of extensible means orpantograph mechanisms, the means employed comprising a cable or cablesor the like, the same being operatively connected to the pantographmechanisms and to an equalizer. This novel equalizer arrange ment isprovided to vary the ratio or movement between the same and thepantograph mechanisms during certain portions of travel of the latterfrom a contracted to an extended position and vice versa.

The invention further comprehends the idea of providing a novelconstructed means or lever arm for movement of one of the sets ofpantograph mechanisms outwardly and away from the opening, this armbeing provided with an eye at the end thereof for the threading of acable or the like for the raising of the mechanism, this arm beingfurther provided at the same end with a notch or the like for engagingextensions on the pantographs for outward movement thereof upon alowering of the same.

Other objects, advantages, features and capabilities are comprehended bythe invention as will later appear, and as are inherently possessedthereby.

Referring to the drawings:

Fig. l is a front view in elevation of a window or opening and showingan embodiment of the invention connected to the sides thereof to providean awning for the same.

Fig. 2 is a vertical crosssectional view taken in the plane representedby the line 2-2 of Fig. 1 and showing the novel awning mechanism in itsraised or contracted position.

graph mechanism and for preventing lateral displacement of the same,could be provided foraccomplishing the same purposes.

Each of these .pantograph mechanisms have at their upper ends lever arms32, 33 and 34, the arm 33 being pivoted adjacent the end of the end link35 by means of a rivet or the like, while the lever arms 32 and 34 areprovided with apertures registering with an aperture adjacent the end ofthe link 36 through which extends a rivet or the like for pivotallyconnecting the same to the link Each of these arms are provided with anaperture at the other end thereof, the arms of the upper pantographmechanisms 10 and 11 being journaled on a cross member or rod 37 carriedby the brackets 12 and 13, while the armsof the lower pantographmechanisms are j ournaled on the cross member 33 carried by the brackets16 and 17.

Similar lever arms 39,40 and 41 are provided at the lower ends of thesepantograph mechanisms, the lever arms of the lower pantograph mechanisms14 and 15 being journaled adjacent the ends of a cross member or rod 42which member or rod has its ends pivotally secured in the lever arms 43and 44 which in turn are pivotally mounted in brackets 45 and 46 securedto the side members 3 and 4 respectively of the frame 1. The lever arms39, 40 and 41 of the upper pantograph mechanisms are journaled adjacentthe ends of a cross member or red 47, this rod having lateral extensions48 or having a part extending laterally of these levers to which areconnected cables or the like 49 for raising and lowering the awningmechaism (to be later more fully explained), these projections beingadapted to engage with the end oi lever arms 50 and 51 pivotallyconnected to the brackets 16 and 17 on the side members 3 and 4respectively, when the upper pantograph mechanisms are lowered.

These lever arms 50 and 51 are channel shaped as clearly shown in Fig.11, the side portions 52 and 53 having arcuate shaped notches 52 at theends thereof for reception of the extensions 48 of the cross bar 4". Theside portion 52 is provided with an extension 54 bent laterally and overthe end of the side 53 to provide an eye or opening at the end of thelever for the threading of the cable 49 therethrough. The central or webpart 55 is provided with an extension 56 bent back upon the web 55 toprovidea smooth and rounded surface for passage of the cable 49thereover.

The lower end of the cable 49 on each side of the opening passes aroundpulleys 57 or the like mounted on the lever arms 43 and 44 andisanchored by any suitable means to the side members 3 and 4, as clearlyshown in the drawings. It will accordingly be seen that upon movement ofthe upper awning mechanisms, the lower awning mechanism willsimultaneously be raised or lowered therewith.

For raising and lowering the upper awning mechanism, cords or cables 58of substantially equal lengths are provided, these 62 on the sidemembers 3 and 4, thence over H pulleys 63 mounted on the brackets 12 and13, and then secured or attached to the extensions 48. It is or" course,understood that the cable or cord 49 and 58 may be of t -e same piece,the connection being made to the extensions 48 by way of a loop or thelike. A cord or cable 64 is connected to the equalizer block and passesaround a locking pulley 65 or the like secured to the rail member6 ofthe frame 1.

In the operation of the embodiment disclosed, the equalizer 61 is raisedor lowered by way of the cord 64 and as shown in Fig. 1 of the drawings,a raising of this equalizer will permit the upper pantograph mechanismsto extend and drop downwardly, the lower mechanism during this operationsimultaneously extending and moving angularly away from and outwardlyfrom the opening and in the path of the ends of the lever arms 43 and44. Upon an extension or dropping of the upper pantograph mechanisms,the extensions 48 will engage with the notch at the ends of the levers50 and 51 which likewise causes the upper pantograph mechanisms to moveoutwardly and away from the opening upon a further extension thereof.The angularity of the vanes or slats of these mechanisms will varydepending, of course, upon the extent to which the pantograph mechanismsare extended, as likewise upon the length of the lever arms 50 and 51,43 and 44. Any desired ratio between the length of the arms 43 and 50and the arms 44 and 51 may be had.

The equalizer 61 has a double purpose. This equalizer not only providessuitable means for evenly raising and lowering the awning mechanisms,but it will likewise be noted that there is a factor of reductionbetween the movement of the same and the movement of the cross member47. WVhile the awning is comparatively light or is in a position suchthat the greater component of its weight is along the lever arms, thecables 58 will run considerably faster than the movement of theequalizer. This condition exists until the equalizer rises to a pointopposit-e to the pulleys 62. From this point until the equalizer risesto its extreme top position, the ratio is reversed and has reached apoint where it takes considerable motion of the equalizer to transmitvery little motion to the awning mechanism.
